That is true, but unfortunately there is already that circumstance in the game now. For example Katarina and Nunu. You nearly have to sit there and wait until there is a moment that a maokai knock back, or xin knock up, etc, that is no longer up before you would dare to use your ultimate.
I do understand we don't want to add even more of this, but im sure with some finagling i can get this type of ability to a working order.
